Remote Controlled Home Automation Using Android Application via WiFi Connectivity

Today is a world of advanced ubiquitous mobile applications which are used exhaustively to save time and energy. These applications ease day-to-day life of a common man. Based on these technologies and applications we designed a Home Automation System. In this paper, we propose design and prototype implementation of home automation system that uses Wi-Fi technology and Android operating system. An attractive market for Home Automation System is for busy families and individuals with physical limitations. Users can control electrical appliances in home or office via smart phone. Application will also provide secure notifications and alarm for Burglary, fire hazards and LPG leakage.This project aims at controlling every happening at home or office on your fingers.

Use of Short Assessment of Health Literacy for Spanish Adults (SAHLSA-50) to Determine the Health Literacy Rate of the Spanish-speaking Population in an Urban Emergency Department

Background: The Hispanic population presents a great opportunity in terms of potential improvements in clinical outcomes and cost reduction for interventions through assessing and improving health literacy. While there are various tools to assess health literacy, many do not assess comprehensive Spanish health literacy. Objectives: We sought to determine the health literacy rate of our Spanish-speaking population in the ED using the SAHLSA-50 tool. Methods: We surveyed a convenience sample of 300 patients from October to November 2012 that presented to our busy, high volume, urban ED. All subjects completed the SAHLSA-50 tool and demographic form with Spanish-speaking research assistants. Results: 63.3% were women. 8% were age 18-25, 42% were 26-40, 45% were 41-65, and 5% were 65+. 11% had less than 3 years of school, 30% had 4-6 years of school, and 59% had at least 7 years of school. Overall, 83% respondents were health literate. Those with less than 3 years of school were95% in those with 7 or more years of school. The elderly (65+) reported least years of school completed and had the lowest health literacy (56.3%). Conclusions: There was an overall health literacy rate of 83.0%. Importantly, those with lower levels of education and elderly patients were more likely to not be health literate. As a next step, targeting those with less education and the elder within the Hispanic population may yield the most impact for improving health literacy and outcomes

Photosubstitution kinetics and mechanism of potassiumoctacyanomolybdate(lV) with 5- nitro-1, 10-phenanthroline

859-862The kinetics of thermal reaction of photochemically generated [Mo(CN)7(OH)]4 in basic medium and [Mo(CN)6(CNH)H2O]2 in acidic medium with 5-nitro-1 , 10-phenanthroline [nitrophen] has been studied in buffer solutions of pH 4.2 - 10.6 and ionic strength 8.0 x 10.2 M at 25 °C. The quantum yield for the formation of the photoproducts is found to depend upon the pH, ligand and [Mo(CN)8]4concentrations. The rate constants and quantum yield are smaller as compared to those of 1, 10- phenanthroline due to electron withdrawing effect of nitro group in nitrophen, which makes the latter a weaker ligand. The pseudo first order rate constants and quantum yield values in acidic medium are higher than those in basic medium. The mechanism of the photochemical substitution is different in two media. In acidic medium the reaction rate increases with increase in ligand concentration, while in basic medium, a variation in the ligand concentration does not lead to any marked change in the reaction rate. The reaction rate and the quantum yield are unaffected by the change in ionic strength

Piezoresistive 6-MNA coated microcantilevers with signal conditioning circuits for electronic nose

This paper presents a micro cantilever based piezo-resistive sensor and its fabrication process along with two different techniques for signal conditioning of sensor output aimed for artificial nose applications. The proposed micro-cantilevers feature a special coating of 6-Marcaptonicotonic acid (6-MNA) on one side of the cantilever which leads to a selective reaction of the target analyte molecules with the functionalized cantilever surface. Two signal conditioning schemes, a novel current excitation method and a resistance to frequency conversion (RFC) method using a new proposed circuit are implemented to precisely read the piezo-resistance changes. Current excitation method is implemented using commercial ICs while RFC method is implemented using a low-power test chip constituting of instrumentation amplifier, buffer and comparator in 180nm mixed-mode CMOS technology. It is shown that the implemented RFC method provides a resolution of 5ppm and is useful for low-cost on-chip measurements involving the piezo-resistive sensors. Implemented current excitation method provides measurement resolution of 40 parts per billion with minimum SNR value of 5 dB which is better than previously-reported values

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

Background Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. Methods We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). Findings In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683–0·717]). Interpretation In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. Funding British Journal of Surgery Society
